After a 50-year temperature record in Scandinavia (-37,5°C in Nikkaluokta, Sweden on 29. November 2021: https://mkweather.com/brutally-cold-weather-in-scandinavia-legendary-frosts-in-sweden-375c-norway-369c-and-finland-340c-and-below-40c-is-forecasted-the-coldest-seasonal-temperatures-in-50/) and a 50-year record in France (-10,0°C in Grenoble, southern France on 30. November 2021: https://mkweather.com/grenoble-france-384-masl-100c-the-coldest-temperatures-in-the-region-minimally-in-the-last-50-years/), the next extreme record from continental Europe!
While in warm and cold fronts already have shifted above Central Europe from Switzerland eastward, and is bringing blizzard conditions from Eastern France to Ukraine /https://mkweather.com/europe-hit-severe-snowstorm-10-30-rarely-up-to-50-cm-of-snow-is-reported-from-eastern-france-central-europe-baltic-region-and-balkan//, Swiss basins and valleys around 500 – 1000 MASL already have received extreme snowfall amounts!
Linthal, a village in canton Glarus in Switzerland, 650 MASL, according to DWD and Meteo Schweiz reports almost 0,5 meters of snow from the blizzard in elevations only around 800 MASL!
49 cm of snow was reported from the village on 30. November 2021 and until Friday, 3. December 2021, the next severe snowfall is forecasted!
Meanwhile, Koetzchach, Austria, 709MASL, reported on 30. November, evening, 38 cm /https://ogimet.com/cgi-bin/gsynres?state=Austri&osum=no&fmt=html&ord=REV&ano=2021&mes=11&day=30&hora=22&ndays=1&Enviar=Ver/.
Total snow cover in the region will very probably stop between 50 – 100 cm in the next days, or in a longer period until 10. December 2021 (after 10.12. warming up is already forecasted).
Alpine densely populated basins and valleys below 1000 MASL are therefore fully prepared for possible extreme frosts in the first December 2021 decade.
The temperature on a deep snow cover should fall in these valleys below -20°C, -25°C, or maybe even -30°C!
We are still waiting for a confirmation of extremely cold outputs, in which historically cold air from Scandinavia will flood Central Europe in the next 10 days.
-20°C is somewhere in Central Europe is very probable, -25°C probable, and -30°C is not fully excluded so far, mainly near heavy snowfall, weak winds, and anomalously dry air combinations.
The situation in Europe we will furthermore watch and will be bringing fresh news about measured weather records and updates of forecasts.
